What are the precautions before the construction of the floor heating system?

Answer: First, the installation of the floor heating main.

1. The installation of the supervisor must be constructed in the position indicated in the design drawings, and there shall be no error 2. The supervisor must do thermal insulation;

3. The installation of the supervisor should be horizontal and vertical;

4. The supervisor should be fixed firmly with a pipe clamp;

5. After the installation of the supervisor, the suppression test should be done.

Second, the installation of floor heating water separator.

1. The installation of the water separator should be kept horizontal;

2. After the installation of the water separator, it should be wiped clean;

3. Pay attention to the connection of water supply and return;

4. After the installation of the water separator, the heating area of each circuit needs to be marked.

3. Laying of floor heating pipes.

1. Consistent with the design circuit.

2. The spacing of pipeline laying is consistent with the design.

3. If the difference in the actual laying length between the pipeline circuits is greater than 30 meters, it is necessary to readjust and notify the company in time.

5. Resolutely put an end to the phenomenon of pipeline crossing.

6. The ground part of the pipeline connected with the water separator must be insulated casing.

I heard that Beijing Glanxuan Company is good, you can go and find out.

1. Review the ground elevation.

2. Local waterproofing (bathroom, kitchen, etc.).

3. If there are other units on the ground, it is necessary to lay buried pipelines or wires in writing.

4. When the heating pipe circuit passes through the door sleeve, it is necessary to confirm whether the laying position of the floor heating pipe hinders the construction of other units (especially the space for floor plugging when the hardcover unit has something to do with the glass floor plug door).

1.Base treatment: thoroughly clean the existing ground, remove dust, floating debris, ensure that the base is dry during construction, for the rough sand base, use wire brushes and other tools to deal with the sand parts, chisel off the loose or too high part, with 1:

1. Sweep the cement mortar to ensure that the new and old concrete are firmly combined.

2.Laying polystyrene board: laying a 20mm thick polystyrene insulation board on the leveling layer, pasting the seam of the board firmly with tape, laying aluminum foil or sticking a layer of composite aluminized polyester film with coordinate grid lines on the insulation layer, and laying the insulation layer flat.

3.Set up elastic isolation belt: paste 20mmx60mm polystyrene slats along the wall with latex, and the paste is required to be flat and tightly lapped.

4.Lay the coil and fix: according to the design requirements of the spacing of the heating pipe (PB pipe), in order to ensure the uniform spacing of the coil, the pipe is fixed on the polystyrene plate with a plastic pipe clamp, and the coil spacing deviation is controlled within 10mm.

5.Set up the boundary lattice seam: when the side length of the radiant heating floor is more than 4m or the area is more than 6, the extruded plastic board separator with a longitudinal and horizontal direction of 20mmx60mm is arranged every left and right, and the height of the slats is 20mm higher than the ground.

Between the corridor and the living room, at the doorway and other cross-sectional mutation parts, a separate polystyrene board separator is made to divide the ground of the two adjacent areas.

6.Fine stone concrete compaction and calendering: fine stone concrete is poured in two times with a thickness of 40mm.

When pouring concrete for the first time, manually wipe to the level of the coil height, and after a week, after the concrete reaches a certain strength, the second pouring is carried out, and after rolling to the slurry, the first calendering is carried out with a trowel, and the second calendering is carried out before the final setting of the concrete.

7.Curing: Within 12 hours after the concrete calendering, watering and curing should be carried out, and the curing time should not be less than 7 days, and the watering times should be able to keep the concrete in a wet state.

8.Finished product protection: When pouring concrete, do a good job of protecting the geothermal pipes to prevent damage to the geothermal pipes. Before the concrete strength is reached, it shall not be stepped on or stacked, and any construction load shall be prohibited.

Before the construction of the underfloor heating system, it is necessary to pay attention to safety issues. Before laying the boundary insulation strip, the wall should be cleaned to ensure the flatness of the wall and avoid the insulation strip falling off during construction and use. Boundary insulating strips should be affixed to all walls and cylinders where the heating area intersects with the ground.

The boundary insulation strip should have a good sticking firmness to ensure that it will not fall off during use. The thermal insulation strip should have a certain stretch performance, which can ensure that the backfill layer plays a buffering role after being heated and expanded.

1.Due to insufficient communication in the early stage, the heat dissipation value of the coil does not match the heat load required by the space, resulting in the situation that the coil cannot be heated up in the later stage. If you have tatami mats at home, some people just encrypt the coils in other areas of the room.

In fact, this effect cannot satisfy the heat of the space. The adjustment plan is not remedied in time, and the temperature in the later stage is not enough. This is also the reason why some people use wall-hung boilers of the same brand.

Because of the slight changes in the installation, the fault repair rate is different, which is also the reason for communicating with the window sealer on site.

2.When choosing a reflective film, choose a product that is resistant to strong alkalis. The reflective film should be laid flat to minimize wrinkles.

The tight points that should be covered by the film should not have the phenomenon of leakage of insulation board and ground. After the underfloor heating construction is completed. The commissioning personnel should adjust the temperature of the room controlled by each piping system according to the design requirements, and some rooms should not have the problem of heat or non-heat.

3.There are only a few HVAC companies on the market that can really apply design standards to the ground. The HVAC company with standardized construction not only has design and construction standards, but also meticulous quality control, pushes the standards to the ground, and truly realizes the standardized construction technology of the whole process, so that customers have no worries.

The way the underfloor heating dissipates heat determines that it heats the floor, and then after the overall temperature of the floor rises, it dissipates heat evenly into our room. In this way, our furniture is affected by radiant underfloor heating. Because our home is installed directly on the ground, it is in direct contact with the heated floor.

The above is the answer to the question of what needs to be paid attention to before the construction of the floor heating system.

Before construction, first inspect the installation of the TEA warm coil, and consider whether the hydraulic test of the new house is qualified, and complete the concrete filling within 48 hours. The heating pipe is installed, and the water pressure setting test is qualified. When installing, it is necessary to determine whether the concealed project has been accepted to prevent unnecessary troubles in the later stage.

It should be noted that the ground must be cleaned before construction, it must be cleaned very clean, and the line also needs to be laid, pay attention to the problem of water leakage, and do not let there be too much dust around.

It is necessary to pay attention to the coordination interface of water and electricity, which must be reserved in place, and to ensure the smoothness of the construction surface, the concealment of other grounds, and finally confirm in the construction area.

Now there are more and more people heating with floor heating, the selection of floor heating floor and floor heating floor construction has also become one of the popular topics of discussion among the public, the floor heating floor is not only very particular about the choice of materials, but also the installation process is required to be very accurate, what are the steps of floor heating floor construction, what should be paid attention to? Take a look at the details below!

1. The floor heating floor should be treated before construction to make the ground dry. The temperature of the underfloor heating test should be at least 50 degrees Celsius, so as to ensure its normal operation. The reeds should be kept warm for more than 24 hours to dry the ground and ensure that the water content meets the standard.

2. Due to the particularity of the underfloor heating method, the amount of moisture released by the heat is extremely important due to the amount of water and heat resistance, therefore, it is necessary to try to prevent the moisture from making the floor moldy, so the hanging method must be used for hot floor construction. The flooring material must pass through the seam material and then connect the floor.

3. Keep the floor clean before starting the floor heating construction, and keep enough expansion joints to lay the carpet. The distance to the expansion joint should be at least 5 cm, and the space must be sealed with tape. At the same time, the use of baseboards that are thicker than ordinary floors requires construction.

Flooring can only be preheated 24 hours after installation. To facilitate heat transfer, the bonding material should not be too thick.

1. It cannot be cross-mixed and laid. When laying the floor, it is not possible to cross-mix the structure. Once the laying is complete, the floor should dry for more than two to four hours to fully cure the adhesive.

2. Moving furniture will not affect floor heating, try not to put furniture without legs on the heated floor, and do not install the accessories of the house on the floor. This is because the warm air in the room radiates from the floor to the entire room. If the heat dissipation surface is blocked by a large area, the heat dissipation in the room is not smooth, and the floor is easy to deform.

3. When using floor heating for the first time, the temperature must rise slowly. Because when the temperature increases strongly, it is easy to cause deformation of the floor.

Floor heating is more popular, and the heating effect is much better than traditional heating. And it has good coverage, you can feel warm in **, so that your winter will not be very cold. When laying, it is not only necessary to choose a more environmentally friendly and durable floor to lay.

Be sure to pay attention to the fact that when building a heated floor, you can't cut corners. Once you cut corners, the follow-up maintenance to open the floor not only costs a lot of maintenance, but also may need to move the furniture of the whole house, which will be a big project, so this key attention needs to be paid attention to.

Underfloor heating systems are not suitable for all buildings. At present, there are two main forms of geothermal heating, one is water heating and geothermal heating, that is, metal pipes, plastic pipes, etc. are buried in concrete floor slabs to provide hot water heating by coal-fired, oil-oiled, gas-fired boilers or electric boilers; The other is electric geothermal heating, that is, the heating cable is buried in the concrete floor slab, and 220V electricity is used for direct heating or heat storage.

For residential houses, underfloor heating is only suitable for bathrooms and kitchens, because there are many furniture in bedrooms, living rooms, and studies, which on the one hand hinder the dissipation of geothermal heat, and on the other hand, high ground temperatures will also deform and damage the furniture. To install geothermal heating, it is necessary to lay a concrete cement layer on the cable (direct heating 3-5 cm, heat storage 5-8 cm), which greatly increases the load on the floor slab. Therefore, buildings with geothermal heating must carry out special calculations during the structural design phase to increase the structural strength.

Geothermal heating of the floor can not be laid with solid wood flooring, because of the installation.

Cement nails in the keel can damage water pipes or cables. There is also a big problem with laying laminate flooring, as we all know, a layer of styrofoam must be laid under the laminate flooring, but this styrofoam layer is a thermal insulation material, which will seriously hinder the heat dissipation, and if the styrofoam layer is not laid, the service life of the laminate floor will be greatly affected.

Nowadays, many businesses claim that flooring can be used for geothermal heating systems, which is actually misleading consumers. According to reports, the vast majority of floors on the market, such as 12-18mm thick solid wood floors and bamboo floors, are not suitable for ground heating radiation systems, otherwise they will affect heat conduction or cause floor deformation. Generally speaking, laminate flooring is more suitable for geothermal flooring, which is pressed at high temperatures and has a low internal moisture content, so the floor will not be deformed due to water dispersion and loss.

Geothermal heating has very high requirements for the floor, including the following four aspects: high substrate density and good internal bonding strength; The expansion rate of water absorption thickness should be less than or equal to; Formaldehyde emissions are as low as possible; Thermal conductivity is crucial.

After the construction is completed, it is better for the owner to check the use of geothermal energy, first of all, the hydrostatic test. The specific steps include: the first step is to slowly fill the water through the water separator, and at the same time discharge the air in the pipeline; The second step is to check the water tightness after being filled with water; In the third step, the manual pump is used to slowly increase the pressure; The fourth step is to increase the pressure to the specified test force, stop the pressure, stabilize the pressure for 1h, and observe whether there is water leakage; In the fifth step, after 1 hour of pressure stabilization, the pressure is made up to the specified test pressure value, and the pressure drop within 15 minutes does not exceed the qualified level of no leakage.

During the commissioning, the initial heating should be slowly heated, the water temperature should be controlled in the range of 25 -30 for about 20 hours, and the water temperature can reach the normal range within 24 hours.

1. A bai must be looking for a professional knowledge of floor heating

Recognize the construction team. "Three.

zhi points dao floor, seven points installation" version, if the decoration team is an amateur right to lay the effect is not good. The tightness of the underfloor heating system must be checked before paving. The ground must be dry (which can be judged by experimental phenomena), and the moisture content of the cement floor should be preferably lower; The indoor humidity should not be too large, regardless of whether there is geothermal heating, the ambient humidity is about 60 degrees before and after installation.

2. It is strictly forbidden to nail the ground during construction. After the construction is completed, nailing is also prohibited on the ground to prevent damage to the heating coil. Before laying laminate flooring, EPE composite film should be laid (EPE composite film must be marked with the words "special for floor heating radiation)" to isolate moisture and release moisture from the surrounding baseboards.

The keel should not be laid. The thermal conductivity of the air is small, which will affect the heat dissipation effect and cause damage to the pipe.

3. When laying the floor, it must be used with special glue for floor heating to increase the use time and effect, and it will not emit toxic gases. Leave a sufficient expansion joint between the floor and the wall, and use a skirting board that is thicker than the current floor. The paving of the ground and the installation of the baseboard should be carried out in two phases.

48 hours after laying the floor, wait for the glue to dry completely, remove the fastener and then make the baseboard. It takes 24 hours after installation for the floor to be heated.

Questions about the construction of underfloor heating.

1 .How much does the floor rise when the floor is laid?

Answer: The elevation of the ground after laying underfloor heating is like this:

The floor heating of the laminate floor will be raised higher than the height of the original floor: about 5 cm (about the cement layer of the insulation board).

2.How to find the leveling, and how to deal with the height difference between the floor and the floor tiles?

Answer: Regarding the leveling after floor heating, generally speaking, it is best to cement leveling or directly lay floor tiles within 24 hours after the heating cable is laid.

If there is a drop between the room without floor heating and the room with floor heating, it can be dealt with by thickening the cement layer or raising the floor keel (it is a wooden floor room), as well as a variety of methods such as crossing stones, but the specific method is determined according to the site.

3.The sequence of connection between floor heating and other work.

Answer: About the connection between the floor heating construction and the decoration company's process:

Step 1: When your house starts, the plumber enters the site, and our floor heating engineer goes to the site to explain to the plumber master about the need for the circuit to be released from the distribution box separately.

Step 2: The first construction should be the floor heating part of the bathroom;

The big conditions that need to be met are: waterproofing is done, the closed water test is qualified, the wall tiles are pasted, and then we are notified to go to the floor heating construction. (After the floor heating is laid, the decoration company needs to directly lay the floor tiles).

Step 3: After the carpentry construction is completed, you can notify the floor heating company to build the floor heating in the living room, bedroom and other areas. (Within 24 hours after the floor heating is laid, the cement leveling of the decoration company is completed).

Step 4: The painting and flooring are finished, and when the decoration is nearing completion, we go to the site to install the temperature control system.
